Hi,
I have a workflow that uses unique status names to align with the work that my team does, eg "Script" and "Sync" (shown below)

I am trying to make an automation rule that creates subtasks once the parent issue moves into a particular status. However, this does not appear to be possible? Only a handful of basic statuses are there?

Have I made a mistake, or is this a limitation of automation? If it isn't possible to use my custom statuses, what is the best solution? Creating a custom field that updates when the status changes and then using that as a trigger instead perhaps?
